来源：环球网 【环球网科技综合报道】10月22日消息，受空气密度和水汽含量变化的影响，宇宙中的电磁波在穿越地 球大气时传播速度会减慢，从而产生对流层延迟。这种延迟被认为是甚长基线干涉测量（VLBI）和全 球导航卫星系统（GNSS）定位中的主要误差来源。如何精确建模与预报这种延迟，成为了当前天文观 测与大地测量领域亟需攻克的重要课题之一。 对此，中国科学院新疆天文台李明帅团队，利用南山26米射电望远镜台址的多年GNSS和气象观测数 据，构建了一种融合门控循环单元（GRU）与长短期记忆网络（LSTM）的混合深度学习模型。该方法 属于人工智能技术的重要分支，可自动从大量观测数据中学习大气延迟变化规律，从而实现对天顶对流 层延迟（ZTD）的高精度短期预测。 针对传统经验模型难以捕捉复杂非线性变化的局限，研究团队引入深度学习架构，将GRU用于提取短 期变化特征，LSTM用于记忆长期趋势，两者结合后形成"混合神经网络"，既能捕捉大气延迟的短时波 动，又能识别其长期规律。结果显示，该模型的预测误差仅约为8毫米，相关系数达96%，显著优于传 统统计模型和单一神经网络。 高精度的对流层延迟预测结果，可有效提升VLBI观测的大气 ...
